We are working on adding stream support to arrayfire. This requires a minor code overhaul on our end. So we don't have it planned for any particular release. This will be a more of "when it is ready feature". I am sorry about not being of more help. But if you have any bottlenecks with arrayfire in its current form, please ask specific questions over here.
